assert that string starts with a given string

[fredr]

Added startWith() for asserting that a string starts with a given string.

[travisjeffery]

what's the use-case? when are you doing this often enough that it makes sense to not use '"foobar".should.match(/^foo/)

[btd]

Agreed @travisjeffery , i think we can close this.

[fredr]

Well, should.js is an expressive library for asserting, and imo 'http://www.example.com/something/something'.should.startWith('http://www.example.com') is more readable than doing a regexp.

But yes, it is possible to regexp matches that does the same thing. This PR is just a suggestion

I agree that startsWith('...') is more readable than using a regexp in many cases. Especially when looking for characters that must be escaped in a regexp such as:

someUrl.should.startWith('http://') compared to someUrl.should.match(/^http:\/\//)

[btd]

someUrl.should.startWith('http://') compared to someUrl.should.match(/^http:\/\//)

this definitely makes sense

[travisjeffery]

@gabrielf yeah that's a good use-case/example

[fredr]

@btd hmm, did I do something strange while merging here? or does the PR look ok?

[btd]

@travisjeffery looks ok for me, what do you think?

[travisjeffery]

Good, just wanted to squash those commits.

[travisjeffery]

Ayee, that boinked attribution. One sec.
